Patented Mar. 25, 1930 VITALIS M. KLOSSpOF MINNEAPOLIS, MINNESOTA BOTTLE-CAPPING MACHINE Application led November 17, 1928.

My present invention has for its object the provision of a highly ecient bottle capping machine and more particularly to such a machine for handling' milk and cream bottle caps or stoppers of the same general type as .dis-

closed and broadly claimed in my United States Letters Pat-ent 1,638,207 of date August 9, 1927 and entitled Bottle stopper.

This type of cap or bottle stopper 1s blanked from sti paper and thereafter intermediately folded upon itself to form an upstanding rib or flange that affords a linger piece by which the cap may be gripped by the lingers and lifted from its seat in the flange l'neck of a milk or cream bottle. Said rib or flange also affords a diametrically extended stifiening member for the cap fwherebythe same may be formed` from relatively light paper stock. j

The aims of this invention are to provide a capping machine that will successfully and efficiently fold cap blanks of this type as the same are fed into the machine to complete said capsby forming ribs orrflanges thereon and thereafter apply the completed caps to seats therefore in the necks of milk or cream bottles as they are successively positioned in the capping machine.

To the above end, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings; which illustrate the invention, like characters indicate Vlike parts throughout the several views.

The bottle cap A heretofore referred to, primarily as it is cut from stiff paper, comprises a blank B having two semi-circular portions connected by an intermediate portion having in its ends V-shaped notches, as shown in Fig. 6. This blank B is folded upon itself at its intermediate portion to form an upstanding diametrically extended rib or liange C. The formation of this rib C brings the semi-circular portions of the blank B into positions in which they form a complete circle which fits on a seat D in the flanged neck of a milk or cream bottle E. This rib C affords a finger piece which may be gripped between the fingers to lift the cap from its seat D in the bottle Said rib C also affords a stiffening member for the cap A. It will be noted that the outer wall of the flanged neck of the bottle E is upwardly tapered.

Referring now in detail to the capping inachine illustrated. The same is provided with four complete and independent capping heads, but, of course, the machine may have only one head or any desired number. This machine has a driven central shaft l0 mounted in suitable bearings to turn about a vertical axis. For the purpose of this case, it is not thought necessary to illustrate the driving means for the shaft l0. Rigidly secured to the upper end of the shaft 10 is a bracket having four equally spaced radially extended arms 11. Supported from each arm 11 is a capping head 12 and under each of said heads is a carrier 13 for one of the bottles E mounted on a conical base 14 for independent raising and lowering movements in respect thereto and the heads 12. The shaft 1() extends through the base 14 at the Kaxis thereof and which base isrigidly securedfto- `said shaft for rotation therewith.

Each bottle carrier 13 is provided with a depending stem 15 which projects below the base 14 and has on its lower end la 'bracket 16 in whicha roller 17 is ournaled and arranged to travel an endless course onaV fixed cam plate 18. ICoiled springs 15 lencircling the stems 15 arecompressed between the base 14 and' bracket 16,y under strain to retract the bottle carriers 13 in respect to the base 14 and hold the rollers 17 on the cam plate 18. Under 'the' rotary action of the shaft 10 the capping lheads 12 and bottle carriers 13 areV f the one will suiiice for the others. 'Referring now in detail to one of` these capping'heads 12`the same, as shown, comprises a pair of relatively heavy upper and lower'rectang'ular plates 19 and 20, respectivelyi These plates 19 and 20 are rigidly but dtachably 4connected by four'screws'21V at the corners of said plates and arel intermediately connected by a pair offsimilar screws 22.' Said plates 19 'and 20 are'hel'd vertically spaced Iat the inner `end of the5 head 12'by 'a' spacing plate 23 andat their outer ends by la pair of' spaci'ng'wash ers 24.

. The spacing plate 23 extends thefull width of the head 12 and is heldin place by the inner pair of screws 21 and the screws 22. Said spacing washers 24 encircle the outer pairvof screws 21 and are `held in placethereby. This spacing of the plates 19'and 20=leaves a'shal-A low passageway 25`therebetween for an intermittently reciprocated cap feedingblade'26.

Extending vertically through the head 12 atthe inner end portion thereof is aplunger passageway 27. Integrally formed with the upper plate 19 in axial alignment with the plunger passageway 27 is a long upstanding sleeve-like bearing 28 for a vertical movable plunger 29, having on its upper end a short stem 30 which is slidably mountedin the ex panded socketed lowerendV portion 31 of a long upright stem 32. 'Y

Integrally formed-with the lower plate 20 insaoos at the under sideY thereof and in axial alignment with'the passageway 27 is a bottle centering member 33. This bottle centering member 33 is in the form of a boss recessed to form anannular bottle engaging surface 34 that surrounds'the passageway 27 and with which the-top of one of the bottles Eengages during the capping thereof, see Fig. 4.' The annularinternal wall centering recess inthe member 30 is upwardly and inwardly tapered, to receive the" tapered flanged neck of the .bottle E. Vhen the flanged neck of the bottle E 'is moved in the centering member 30,

vt-he internally taperedrwall thereof engages saidflangerneck, moves the bottle E on its carrier 13 with a cam actionand axially centers' said bottle in rrespect to the passage-L Vway 27."

To further assist in centering a bottle E in respect to the passageway 27 cam-acting lugs 35 are formed with the centering member 33, circumferentialvly spaced therearound on the lower end of said member and form depending extensions thereof.v The inner face ofthe cam lugs 35'havethe same taper as the internal wall of the centering member 33. It is only when a bottle lE is placed on the carrier'13 considerably out of center that the cam lugs 35 act thereon.

l 'A pairof diametrically extended combinedA cam and stop pins '36`are anchored tothe 'socketedstem member 31 and extend through vertaalslag a7 in thefbearing as. yThe head i f 12 is gravity held in its lower most position'V by the engagement of'its bearing 28 at its upper ends kof the slots 37with-v the pins 36. The mounting of the campins 36 in the slots 37 holds the head 12 from turning ab'out f i the axis of the stem32.Y reference'to Fig. s

4, it will be noted thatthe passageway 27 in the lower plate 20 has the sameV diameter as the bottle seat D.' The socket member 31 is of the same external diameter as 'the' plunger 29 'and slidably work's'in the bearing 28. A cross lbar 38, that is square in ycross section, extends diametrically through the plunger stem 30 at the upper end of the plunger 29 with its fend portions; extendingthrougha pair of'diametricallyy opposite vertical slots 39 in the bearing 28 and outward thereof.

This bar 38 holds the plunger ,29j from turn` ing `about its axis' in the passageway 27 and .by its engagement with the bearing 28, at

the ends of the slots 39, limits the stroke of the plunger 29 in respect to the head 12. In the retracted or upper position of the plunger 29, its lower or outer end is flush with the inner face of the plate'19 and when projected it extends into the neck ofthe bottle E when in the centering member 33. Y

A coiled spring 40has one of itsends an- 4chored to a fixed radially `projecting pin 41 on thek upper end portion ofthe'bearing 28 and its other Vend is attached to the inner end of the cross bar 38 and is under strain to retract the plunger 29. y

The head 12 is yieldingly held suspended by the stem 32, the upper end portion of which extends through a bearing 42 on the outer end of the overlying arm 11 and a bearing 43 overlying the bearing 42, vertically spaced therefrom and integrally formed with a bracket 44 rigidly secured to said arm. A key 45 on the bearing 42 extends into a key-way in the stem 32 and holds said stem from turning about its vertical axis but with freedom for limited endwise sliding movement in thebearings 42 and 43. Applied to the upper end of the stem 32 is an adjusting nut 46 which normally engages the upper end of the bearing 43 and sustains said stem and hence the head 12 from the arm 11. A coiled spring 47 encircling the stem 32 between the bearings 42 and 43 is compressed between the bearing 43 and a cross pin 48 in said stem and yieldingly holds the stem 32 in its normal or lowermost position.

A skeleton magazine is provided for holding a stack of the cap blanks B with the lower end of the stack in an intake passageway 49, formed in the plate 19 at the opposite end thereof from the passageway 27, and supported on the feed plate 26. This passageway 49 in cross section has the same contour as the cap blanks B and holds the same properly positioned to be moved by the feed blade 26 into the passageway 27, as will presently appear.

The magazine 50 comprises, as shown, four upright rods circumferentially spaced around the intake passageway 49, with their lower ends anchored to the head plate 19, for holding the cap blanks B in an upright stack aligned with the passageway 49. A springpressed follower 51 is provided for feeding the cap blanks B downward through the magazine 50, into the passageway 49 and onto the feed blade 26. This follower 51 is in the form of a flat disc which rests on the top of the stack of cap blanks B and is provided with a long upstanding stem 52 which works through an aperture in a cross-tie bar 53 and is guided thereby with freedom for endwise movement. A coiled spring encircling the stem 52 is compressed lbetween the follower 51 and cross-tie bar 53 and yieldingly holds said follower pressed onto the stack of cap blanks B. Said cross-tie bar 53 is rigidly secured by pairs of opposing nuts 54 to the upper ends of a pair of upright rods 55 the lower ends of which are anchored in the head plate 19.

The feed blade 26 is reciprocated in timed relation with the plunger 29 to eject the lowermost blank B from the stack and position the same over a thin folding blade 56 which forms the web C to complete the cap A, as will presently appear. This feed blad-e 26 at the same time it is reciproeated to position a cap blank B over the folding blade 56 moves the completed cap A from over the folding blade 56 into the passageway 27 under the plunger 29 to be moved thereby into the cap seat D of the bottle E, as will presently appear. To cause the feed blade 26 to eject only a single 'cap blank B from the stack during its forward movement it is medially recessed at 57 rearward from its inner end portion. This recess 57 is of substantially the same depth and width as one of the cap blanksB and its inner end portion has the same contour as said blank and affords a cap blank engaging shoulder 58.

When the feed blade 26 is in its rearmost position the lowermost cap blank B rests on said blade within the recess 57 and with the rear one-half of its marginal edge portion engaged by the shoulder 58 which holds said blank properly positioned for the folding blade 5 During the forward movement of the feed blade 26 the cap blank B in its recess 57 is ejected from the stack by the shoulder 58 and carried to a position over the folding' blade 56. As the lowermost blank B is ejected from the stack the rear end portion of the feed blade 26 moves under said stack and supports the same. In the front end portion of the feed blade 26 is a semi-cylindrical notch 59 the diameter of which is substantially the same as the cap A. The feed blade 26 at its notch 59 is arranged to engage the rear onehalf portion of a cap A, after the rib C has been formed on said cap by the folding blade 56, when in its rearmost position and move said cap forward and position the same in the passageway 27 under the plunger 29.

The feed blade 26 is rigidly secured at its longitudinal edges to a pair of cross heads 60 slidably mounted in ways 61 formed in the longitudinal edge portions of the head plates 19 and 20, and supports said blade for straight line traveling movement in the passageway 25. For reciprocating the feed blade 26 in the passageway 25 in timed relation to the plunger 29 there is provided a pair of toggle levers 62 which extend on opposite sides of the bearing 28. Each of these toggle levers 62 comprises a relatively short arm pivoted to a bearing lug 63 on the bearing 28 and a long arm pivoted to and between the prongs of a bifurcated lug 64 on one of the cross heads 60. It will be noted that the long arm of each toggle lever 62 comprises two telescoped sections adjustably connected by screw threads whereby the operative length of the toggle may be varied, at will, to properly position t-he feed blade 26. Foractuating the toggle levers 62 to buckle and straighten the same and thereby reciprocate the cross heads 60, and hence the feed blade 26 there is integrally formed on the short arms of said levers a pair of cam heads 65 which cooperate with the cam pins 36 and are actuated thereby.

Each cam head 65 is provided with parallower end of axes of the passageways 27 andrt9 and isV mounted Vfor vertical reciprocatory movements in timed relation to Vthe plunger 29. rlliis folding blade 56 is rigidly secured toi a carrying plate 71 which extends transversely under the head 12 and has at itsends a pair of upstanding arms 72. Ak pair of short depending posts 73 anchored to the head plate 20 extends through bores in the carrying plate 71 and guides the same for vertical movement. Encircling the posts .73 within recesses 7 4 in the carryingI plate 71 are coiled springs i5 compressed between the head plate 2O and carrying plate 71 to yieldingly hold said carrying` plate in its lowermost position with the folding'blade 56 retracted. Said folding blade 56 works through longitudinally extended and vertically aligned slots 76 and 7 7 formed in the head plate 20 and feed blade 26.

Formed in the head plate 19 is a folding groove 78 with which the folding `blade 56 cooperates to produce a die adapted to 'intermediately fold a cap blank B and form the ribs C thereon. rlhis groove 7 8 is formed in the under side of the head plate 19 and extends the full-distance between the passageways 27 and a9 and terminates on the opposite side of the passageway 27 from the passageway 49, see Figs. 2 and 4i. Formed in the the plunger 29 isa diametrically extended groove 79 which is of the same shape and Vand size in cross section as ythe groove 78. 'lll/iis groove 79 when the plunger 29 is positioned, as yshown in Fig. 2, is longitudinally aligned with .the groove 7 8 and forms an intermediate section thereof. Y rlfhe groove 78 also performs another im- .i portant functiomin that it serves as a guide for a cap A during its movement by the feed blade 26 from a position over vthe, folding blade 56 to the passageway 27 and directs the rib@ of said cap into thecgroove 79 in the plunger 29.` 1

The folding blade 56 is raised against 'the action of the springs by a pair of laterally spaced cam heads 80 to cause said blade to en ter the groove 7 8 and intermediately fold a cap blank B and form the yrib C thereon. Thesecam heads 8O attheir lower ends loosely rest on the top of the head plate 19 as a lbase of resist-ance with freedom for compound pivotal and sliding movements longitudinally of the head 12. The upper ends of 'the cam heads 8O engage the under side of a bearing block 81 detachably secured to the under side of the transverse portion ofl a yoke 83. This yoke 83 extends transversely of the head 12 with its arms overlapping the arms 72 on 34e on said the carrying plate 7 land are adjustably but rigidly secured thereto by `pairs ofset screws ,l3y 'reference to Fig. 8, it will bev noted that the screws8t'extend through slots 85 linthe arms of the yo te 81, whereby said 'yoke may Y be raised or lowered in respect to the carryf ing plate 71'to vcause the folding blade 56 i to enter the ,groove`78` the Vproper depth to form the rib C. The cam heads 8O are rigidly connected at theinlower end portions by a arm 86 that is in'V bell crank arrangement therewith and pivoted at v87 tothe adjacent end of the bar 38. The cam heads 80 are actuated by the head 12 and plunger 29 to impart reverse reciprocating movement to the feed blade 26 from that of` saidplunger.

rlhe operation of theiinproved capping machine may be brieflyl described as follows It may beassumed that the capping head 12, which has just been describedin detail,

has been operated a suflicient number of times to position a cap blank B over thefolding blade 56 and a cap Ainthe passageway 27 under the plunger 29 with its rib C in the groove 7 9 of said plunger-` The capping head 12 in normal position is gravity held invits lowermost position with the plunger l29 yieldingly held raised and the feed blade 26 and` folding blade y56ietracted. In this position of the feedI blade 26, its shoulder I58 engages the lowermost cap blank B which'rests on said feed blade and its notched vfront end .,591 is in position to engage-a fcap A overlyingv the folding blade 56.( l

Under th'e'rotation of the capping machine about the axisof the shaft 10 the bottlevcarriers 13 are successively raised and then lowered as Vthe rollers 17 of said carriers pass over the high portion ofthe fixed cam' head 18 and at which time a cap A is applied to the bottle E on ,thev carrier 13 lpassing ,over` the high portion of said cam head 18.

As a bottle E is raised by its carrier 13 the hanged neck of said bottle is-directed intoy the centering member 33 andv automaticallyv centered thereby lin respect to ,the cap passageway-27 and caused to engage the surface b member aridlift thehead 1 2. As

one of the Vcapping heads 12 is lifted by ya bottle E the cam heads 65 carried therebycause their pivots. y the cam heads 6,5 buckle the toggle levers 62 and move the feedblade 26 forward. Said forward movement of the feed blade 26 at its notched end engageslthe cap A positioned over the folding blade 56 and moves the saine into the passageway 27 undertlie plunger 29.

This saine forward movement of thef-eed blade 26, by the engagement of its shoulder 58 with the cap blank B` rest-ing thereon, moves said blank and positions the saine` over the folding blade '56.; During the recipro- Vtheir cam surfaces 69r to engage therelatively kfixed cam pins 36 and swing*saidheads` on This swinging movementv of y cating movement of the feed blade 26 the stack of cap blanks B is supported on the rear end portion of said feed blade. As a cap A and a cap blank B are thus positioned by the feed blade 26 the forward movement of said blade is stopped'by the passing of the cam surface 69 out of contact with the cam pins 36. At the time the forward movement of the feed blade 26 is thus stopped the cam heads 65 have been moved into positions in which their cam surfaces 70 are parallel to the slots 37 and as said cam surfaces 70 pass over the cam pins 36 they hold the cam heads 65 stationary and hence the feed blade 26. It is important to note that when the cam heads 65 are stopped in this position the cam surface 68 overlies the cam pins 36, as will presently appear.

During the forward movement of the feed blade 26 under the lifting action of the head 12 the spring 40 has caused the plunger 29 to move upward with said head until stopped by the engagement of the bar 38 with the socket member 31 and at which time the feed blade 26 has reached the limit of its forward movement with a cap blank B and a cap A positioned as above stated.

The plunger 29 is now held fixed in respect to the head 12 and further lifting movement o'f said head will cause the plunger to enter the passageway 27 and press the underlying cap A into the flanged neck of the bottle E and on to the seat I) therein.

As is well known, milk or cream bottles vary somewhat in height and to compensate for such difference the spring 47 will yield under a predetermined pressure on the head 12 and allow said head and all parts carried thereby to lift and thereby insure proper seating of a cap A in the bottle E and prevent breakage of either the bottle or the machine o'r both.

v During the capping action of the plunger i 1,29, the movement of the head 12 in respect y thereto will operate the cam heads 80 to lift the carrying plate 71 and thereby project the folding blade 56 through the slot 76 in the feed blade 26 andL into the groove 78 to fold the intermediate portion of the overlying cap blank B by pressing the same into said groove to `form the rib G thereon. At the Y i completion of the capping of a bottle E said bottle is lowered by its carrier 13 under the action of the cam head 18 and the head 12 follows said bottle under the action of gravity to the limit of its downward movement and thereafter the neck of the bottle E moves ment of the yo'ke 83 with the head l2 operates the cam heads 80 to release the carrier plate 71 and permit its spring 75 to move said plate downward and retract the folding blade 56. Further downward movement of the head 12 will cause its bearings 28, at the upper ends of the slots 39 to engage the bar 38 and move the plunger 29 downward with the head 12. During said initial return movement of the head 12 the cam heads 65 are held stationary and hence the feed blade 26 by the contact of the moving cam surfaces over the cam pins 36. At the time the plunger 29 is started on its return movement the cam surfaces 68 engage the cam pins 36 and thereby swing the cam heads 65 on their pivots to straighten the toggle levers 62 and retract the feed blade 26.

The downward movement of the head of 12 is stopped and hence the retracted movement of the feed blade 26 by the engagement of the bearing 28 at the upper end of the slots 37 with the cam pins 36. At the completion of the retracted movement of the feed blade 26 the rearmost cap blank B drops into the recess 57 in the feed blade 26 in position to be engaged by the shoulder 58 during the next operation of the machine to cap a bottle. Also at the completion of the retracting movement of the feed blade 26 the cap A, from the rib C of which the folding blade 56 has just been withdrawn, drops into the notched end 59 of said feed blade to be engaged thereby during the next projecting movement of the feed blade 26. In a broad sense, the intake passageway 49 forms a por- Vapplying member working in the passageway, folding means for forming a rib on a cap blank to complete the formation of a cap, and means for feeding a cap blank to the folding means and for feeding a cap from the folding means to the cap applying member.
